如何在Django中传递下拉列表中的选定值？

from django import forms

class MyForm(forms.Form):
    my_choices = forms.ChoiceField(choices=[('option1', 'Option 1'), ('option2', 'Option 2')])

from django.shortcuts import render
from .forms import MyForm

def my_view(request):
    form = MyForm()
    return render(request, 'my_template.html', {'form': form})

<form method="POST">
  {% csrf_token %}
  {{ form.my_choices }}
  <button type="submit">Submit</button>
</form>

def my_view(request):
    form = MyForm(request.POST)
    if form.is_valid():
        selected_value = form.cleaned_data['my_choices']
        # 可以在这里对选定的值进行处理
    return render(request, 'my_template.html', {'form': form})
